Authorized 3M™ Window Tinting in El Cajon

Stop the Heat. Protect Your Skin. Verify the Authenticity.

You are looking for 3M™ tint because you want the best. But in San Diego, many shops claim to use 3M, but install cheap dyed film instead. At Cali Glass & Tint, we don't just tell you it's 3M. We prove it.

The "Fake 3M" Warning

How to Know You’re Getting the Real Deal

If another shop offers you "3M Tint" for $199, run away. Real 3M film is a premium technology, not a commodity. Here is our promise to you:

See The Box

Ask us, and we will walk you to the stock room and show you the official red 3M box.

See The Watermark

Genuine 3M film has a faint "3M" logo printed on the liner (which we peel off). We will show you this before we start.

The Heat Lamp Challenge

Don't believe the specs? Stand in front of our Heat Lamp display. Feel the difference between "Regular Tint" and "3M Crystalline" with your own hand.
